Blog publishing platform Medium will unveil an iOS app next week, its first foray into mobile since its 2012 launch, according to a Fortune report.

The app is designed for consumption of content rather than creation on the platform, at least initially, Medium co-founder and CEO Evan Williams revealed Thursday night during Fortune's Brainstorm Tech dinner in Menlo Park, Calif. The report did not indicate when an Android version would be available.

Williams, who also founded Twitter and Blogger, also said that the platform's user base has experienced rapid user growth in recent months, ballooning from 9 million unique monthly users in December to its current 13 million count.

Williams' revelations of Medium's expansions come on the heels of news in late January that the startup had closed a $25 million round of funding, which is a hefty amount of money considering the average deal size is around $9 million.

It's Williams' goal to make Medium, a network of writers and editors, a model for curating quality information. The platform, unveiled in 2012, organizes content through collections focused on specific themes.

"We call them 'ideas' and 'stories,' but it can be personal stories or it can be investigative journalism. It can be two paragraphs or 50,000 words," Williams said at the Brainstorm Tech dinner. "On the creation side, it's the easiest way to put a thought out in the world or a story."
